The Doctor's Horrible Experiment

The Doctor's Horrible Experiment (French: Le Testament du docteur Cordelier) is a 1959 French black-and-white television film directed by Jean Renoir. The film is a retelling of the novella Strange Case of Dr Jekyll and Mr Hyde by Robert Louis Stevenson set in 1950s France. Jean-Louis Barrault plays Dr. Cordelier/Opale, the substitute for Dr. Jekyll/Hyde character; the film is also known for its visual style that is far above the normal television programs of the 1950s.

In Paris, the lawyer Joly is given the will of his friend and client Cordelier, a well-known psychiatrist, who leaves everything to a patient called Opale. However Joly learns that this Opale is a sadistic pervert and murderer who keeps evading the police. He even causes the death of another leading psychiatrist, Séverin, who challenged Cordelier's views. The climax comes after a smart party at Cordelier's capacious house, when he is heard howling with pain in his laboratory. Breaking in, Joly finds Opale, who admits he is really Cordelier and makes his confession. Guilt over his sexual exploitation of female staff and patients led him, by long research into mind-altering drugs, to create a separate persona through which he could enact his hidden desires without taking responsibility. Swallowing an overdose, he dies.
